A new very small update has been certified by the PTCRB for the Sony Xperia Z4 Tablet. The build number certified is 28.0.A.8.253, which compares to current version number 28.0.A.8.251. As the Xperia Z3+ and Z4 Tablet have already been fully patched with regards to the Stagefright exploit, expect the update to bring small bug fixes or performance enhancements. We’ll let you know once it starts to roll.
